COMBINED DYNAMO AND DRIVING-G EAR.

SPECIFICATION forming part of Letters Patent No. 709,848, datedSeptember 23, 1902.

Application filed November 18, 1901. Serial No. 82,717. (No model.)

To ctZZ whom it may concern.-

Be it known that I, JoHN L. OREVELING, a citizen of the United States,residing in the borough of Manhattan, city, con nty, and State of NewYork, have invented certain new and useful Improvements in a CombinedDynamo and Driving-Gear, of which the following is a specification.

Myinvention relates to a combined dynamo and driving-gear, and hasreference more particularly to structures wherein the direction ofrotation of the driving power of the machine is subject orliable tosudden reversalsas, for instance, a dynamo carried by a railway-car forthe purpose of car-lighting, &c.

In order to clearly disclose one mode of carrying out my invention, Ihave illustrated the preferred embodiment thereof when the invention isemployed in car-lighting, the same being, so far as I am at presentadvised, the best mode of carrying out my invention.

In the accompanying drawings, Figure I is a side elevation of adynamo-machine and driving-gear embodying my invention as applied toear-lighting, and Fig. II is a transverse section through the machine.

In the drawings, a, is a suitable dynamo, the field frame or casing ofwhich forms a suitable hanger or support for holding the machine inoperative position and whose armature Z) is carried upon a hollow shaft0, which hollow shaft runs in suitable hearings in boxes (Z, carried bythe frame e of the machine. Lubricating-rings f of any desiredconstruction are provided to lubricate the hollow shaft, and channels 9serve to return the surplus lubricant to the boxes d. A clutch member 7bis carried at one end of the hollow shaft and a clutch membert' iscarried at the other end of the hollow shaft.

Passing through the hollow shaft 0 is a suitable shaft j, which shaft jcarries loose pulleys 7t and Z. These pulleys rotate free of the shaft,but are adapted to move longitudinally therewith. Washers m, surroundingthe shaft and adapted to bear against the respective pulleys, areadapted to receive the thrust of the spiral springs 0, held in place bythe heads 1) on the ends of the shaft, the purpose of which flexiblemounting will be explained hereinafter. The pulley carries the mate q ofthe clutch member 7L and the pulley Z carries the mate '2' of the clutcht'. The dynamo is supported from the body 3 of a railway-car, one ofwhose axles t is provided with a suitable pulley u, adjacent to whichare idler-sheaves o to, extending below the said axle.

A belt or other equivalent driving-band is provided for driving themachine. This belt passes around both of the end pulleys of the shaftand the pulley u and idlers o '10.

.2 indicates the car-wheel.

The operation of the construction is as follows: When the machine isdriven, as by a forward movement of the train, one of the clutchessay irwill be in action and the other of the clutches, h will be out ofaction. So long as the direction of movement is not reversed the clutcht' 0 will remain in engagement irrespective of the stops which may bemade; but upon a reversal of the movement of the train the belt a; willmove in a reversed direction, thereby causing the face of the teeth ofthe clutch 0 to bear strongly against the face of the teeth of theclutch i, imparting a longitudinal movement to the pulley Z and shaft jsufficient to cause the teeth of the clutch h g to engage each other,whereupon by reason of the shape of the teeth the clutch h q will gointo action and the clutch t' T will be disengaged and out of action,and the pulley it will carry the load and the pulley Z run idly. Uponanother reversal of movement of the train the opposite effect will beproduced and the clutch t 0' will come into action.

Having described my invention, what I claim, and desire to secure byLetters Pa ent, is-

1. The combination of a generator, asource of power whose motion isliable to reversals, a driving-gearintervening between the source ofpower and the generator and embodying in its structure clutch mechanismand cooperating pulleys placed on opposite sides of the armature adaptedto communicate motion in one direction only to the generator,irrespective of the reversals of the direction of movement of the sourceof power.

2. The combination of a generator, a source of power whose direction ofmotion is liable to reversals and clutch mechanism and cooperatingpulleys placed at opposite ends of the armature: adapted to communicatemotion in one direction only to the generator, irrespective of thereversals in direction of movement of the source of power.

3. In a car system of distribution, the combination of a generator, ahanger therefor, pulleys and cooperating clutch members on each side ofthe hanger, a pulley driven from the axle of the car and an endless beltengaging all of said pulleys.

l. In a system of distribution for railwaycars, the combination of agenerator, a hanger therefor, pulleys on either side of the car-axle andhanger and clutch members and cooperating means intervening between thepulleys, the clutch members of one pulley being entirely out ofengagement when the clutch members of the other pulley are engaged.

5. The combination of a generator, provided with a shaft, a plurality ofpulleys, a hollow shaft concentric with said shaft adapted tocommunicate motion to a movable part of the generator and clutchmechanism intervening between the pulleys and the hollow shaft.

6. The combination of a generator having a shaft, a plurality ofclutches upon the said shaft, one on each side of the generator, and

means whereby one of the clutches is entirely disengaged and the otheris entirely engaged during the entire time it is in service or until areversal of movement of the driving force.

7. The combination in a car-lighting system of a generator having areversible source of power, a movable part, a plurality of shaftsconcentric with each other, a plurality of clutches each clutch havingamember carried by one shaft and a plurality of pulleys each carrying aclutch member, said clutch mechanism being so connected to thegeneratoras to communicate motion thereto in one direction onlyirrespective of the reversals of movement of the source of power.

5. The combination in a car-lighting system of a variable source ofpower, agenerator comprising in its structure a rotary part and a shaftfor driving the same, the said shaft being provided with pulleys one oneach side of the said rotary part and clutches intervening between thesaid pulleys and the said rotary part, whereby the said rotary part isdriven in one direction only.

9. The combination of a generator driven from a reversible source ofpower, a shaft, a

plurality of pulleys concentric with the said shaft on opposite sides ofthe generator and a plurality of positively-engaging clutches adapted tocommunicate motion to the generator in one direction only irrespectiveof the reversals of direction of movement of the source of power.

10. A generator provided with a shaft combined with a plurality ofpulleys concentric with said shaft one on each side of the generator andclutch members each clutch member cooperating with a mate forming a partof the driving-gear of the generator, the said clutch members beingengaged one from the other by reciprocal action and one clutch memberbeing entirely disengaged when the other is engaged.

11. The combination of a dynamo-frame constituting a shaft hanger orsupport and a shaft and a plurality of pulleys, one on each side of thedynamo-frame each adapted to drive the dynamo and means interveningbetween the pulleys whereby the pulleys maybe driven in oppositedirection.

12. In a system of distribution for railwaycars, the combination of agenerator, a casing therefor serving as a hanger or support for thegenerator, and pulleys and cooperating clutches on either side of thesame,each pulley open at one side to permit the application thereto ofan endless belt passing around other pulleys without the necessity ofopening or splicing the belt.

13. The combination of a generator, a dynamo-frame serving as a hangeror support therefor, driving-pulleys for the said generator on oppositesides thereof, and revolving in opposite directions, and a plurality ofclutches, one clutch cooperating with each pulley and means whereby themovement of engagement of one clutch serves to effect the completedisengagement of the other clutch.

14:. The combination with a car of a pulley deriving rotation frommotion of the car ofa generator having an armature and pulleys inproximity to the ends of the armature and clutch members transmittingmotion from the pulleys to the armature in one direction only and anendless belt engaging all the abovenamed pulleys.
